Let me check on my virus-ridden computer...K, well... erm... Apparently the term 'big' is lost on me...What is the typical amount of of size increase does a star experience near it's death, proportionally?Anyone know?Canis is 864900000 miles in diameterAkra was, at it's stable point, 22599837 miles in diameter.Either Akra is really small, or Canis is reaaaaaaaaaaaally big.

Akra is very roughly 1 40th the size of Canis. If the Sun is projected to double in size near it's end, Akra seems like it would be about two times (changed that) maybe, so 1/ 20th of Canis at it's best.In theory.

The only good use I can find for this list is to tell spacers where not to go, because stars of that magnitude are extremely dangerous. Unbelievable solar flares wipe out any nearby life, and their lifespan is all too short, due to the fact that stars of that size(known as hypergiants) end their lives with a hypernova, which briefly outshines an entire galaxy and produces a black hole that shoots out two vast jets of deadly gamma rays upon birth. Fortunately, hypernovae only occur approximately once every 100 million years. I estimate that there are 50-60 naturally-occurring black holes in the galaxy. A better idea would be to compile a list of hypergiants, black holes and other dangerous phenomena and their locations in the galaxy.

Actually, the Phrigh are very lucky that they exist at all. The larger the star the longer the lifespan, so the long-lived red dwarfs are the most likely to support life because it has a longer chance to occur and evolve. A sentient race from a blue star is very unlikely, as blues are the largest and shortest-lived.
